Stereospecific synthesis, structural characterisation and resolution of 2-phospha[3]ferrocenophane derivatives – A new chiral scaffold

The first 2-phospha[3]ferrocenophanes containing stereogenic carbon atoms in the three-atom bridge have been synthesised from phenylphosphane by stereospecific ring-closing phosphanation reactions. Either alpha-substituted 1,1?-bis-(hydroxymethyl)ferrocenes or the corresponding 2-oxa-[3]ferrocenophanes have been used as diastereomerically pure starting materials. The resolution of 1,2,3-triphenyl-[2]phosphaferrocenophane has been achieved by chromatographic separation of the diastereomeric adducts of a chiral cyclopalladate complex. The X-ray crystal structures of two 2-phospha[3]ferrocenophane-borane complexes are also reported. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Electrochemical characterization of ZrTi alloys for biomedical applications

The electrochemical behaviour of three ZrTi alloys (Zr5Ti, Zr25Ti and Zr45Ti) in Ringer’s solution has been investigated. Their resistance against localized corrosion has been determined from cyclic potentiodynamic polarization (CCP) and electrochemical impedance spectroscopy (EIS) measurements, whereas scanning electrochemical microscopy (SECM) was applied to investigate the local reactivity of the passive films developed on the materials, and scanning electron microscopy (SEM) was employed to characterize the surface morphology of the alloys subjected to anodic polarization. An increased reactivity could be detected with SECM when the metal samples were polarized at +0.50 V SHE, though the extent of this feature greatly depended on the nature of the metallic material. In addition, At 37 C, the Zr5Ti alloy was susceptible to localized corrosion. Though Zr25Ti alloy presented rather low pitting potential, the spontaneous corrosion potential of the material was sufficiently negative to require overpotentials around 600 mV for breakdown to occur. Finally, the Zr45Ti alloy exhibited a larger passive range in the polarization curve, and it was resistant to localized corrosion.

Design and synthesis of new functional compounds related to ferrocene bearing heterocyclic moieties. A new approach towards electron donor organic materials

The synthesis of heterocyclic systems incorporating more than one ferrocene unit was shown to be a facile and convenient route for the synthesis of new ferrocene-heterocycles. Hydrazide 2 was prepared and cyclized to oxadiazole, triazole, and pyrazole using the procedures described in this context with good yields. A pyrazolone derivative could not be obtained and instead a hydrazone derivative 17 was isolated. Hydrazide 2 was condensed with aromatic aldehydes and ferrocene-1,1?-dicarbaldehyde derivatives to give the corresponding hydrazones 11a-c and dihydrazones 12, 14 and 18 in high yields. Cyclic voltammetry (CV) of the selected ferrocene-heterocycles 8 and 9 was studied comparing with the parent ferrocene and acetylferrocene. The CV of the compound 8 revealed an additional, quasireversible, one-electron oxidation wave at 849 mV, corresponding to the second ferrocene unit connected to the oxadiazole ring through the SCH2CO spacer.

Diamond nanostructures and nanoparticles: Electrochemical properties and applications

Macro-sized diamond films have been widely applied as the electrode for electrochemical and electroanalytical applications. Due to the non-uniform doping in diamond, boundary effects, and the varied ratios of graphite to diamond, only averaged electrochemical signals are detected over the full electrode. The studies of diamond electrochemistry at the nanoscale are thus highly required. In this chapter we overview recent progress and achievements about electrochemical properties and applications of diamond nanostructures and nanoparticles. After a brief introduction of the formation of these nanostructures and nanoparticles, electrochemical behavior of diamond nanostructures (e.g., diamond nanotexures, nanowires, networks, etc.) and nanoparticles (undoped, doped nanoparticles) in the presence/absence of redox probes is summarized. Their electroanalytical (e.g., electrochemical, biochemical sensing, etc.) and electrochemical (e.g., energy storage using capacitors and batteries, electrocatalysis, etc.) applications are shown. Diamond nanoelectrode array is introduced and highlighted as a promising tool to investigate diamond electrochemistry at the nanoscale as well.

Nanoarchitectures based on multi-walled carbon nanotubes non-covalently functionalized with Concanavalin A: A new building-block with supramolecular recognition properties for the development of electrochemical biosensors

We propose an innovative nanoarchitecture for the development of electrochemical biosensors based on the non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) with the lectin Concanavalin A (ConA) and the site-specific supramolecular binding of glycobiomolecules. As proof-of-concept, we propose the use of two glycoenzymes, glucose oxidase (GOx) and horseradish peroxidase (HRP), for building mono and bienzymatic glucose biosensors. The selected conditions for the preparation of the dispersion were 1.5 mg MWCNTs in 1.0 mL of 2.0 mg mL?1 ConA sonicated for 5.0 min with sonicator probe. The monoenzymatic glucose biosensor was prepared by casting GCE with the MWCNTs-ConA dispersion (GCE/MWCNTs-ConA) followed by the interaction with GOx (GCE/MWCNTs-ConA/GOx), while the bienzymatic one was obtained by interaction of GCE/MWCNTs-ConA with GOx + HRP (GCE/MWCNTs-ConA/GOx-HRP). The best analytical performance was obtained with the bienzymatic biosensor from the amperometric response at -0.050 V in the presence of 1.0 ¡Á 10-4 M hydroquinone. The sensitivity was (2.22 ¡À 0.03) muA mM?1 (which was 5.2 times higher than the one obtained with the monoenzymatic biosensor) and a detection limit of 0.31 muM. The reproducibility was 5.4% and the biosensor was challenged with human blood serum showing an excellent correlation with the values reported by the laboratory.

Organometallic-Organic Hybrid Crystals from Ferrocenyl Dipyridine and Binaphthol: Different Crystal Structures and Nonlinear Optical Properties Depending upon the Reaction Medium and Optical Purity of Binaphthol

The hydrogen bond directed molecular recognition between 1,1?-bis(ethenyl-4-pyridyl)-ferrocene (1) and (¡À)-1,1?-binaphthol (2)/(-)-1,1?- binaphthol ((-)-2) has been studied by cocrystallization in different solvents. Single-crystal X-ray structures reveal that 3:2, 2:1, and 1:1 complexes (3, 4, and 5, respectively) of 1,1?-bis(ethenyl-4-pyridyl)ferrocene (1) and (¡À)-1,1-binaphthol (2) are formed in tetrahydrofuran, methanol, and ethanol, respectively. 5 has a noncentrosymmetric packing arrangement, and an efficiency of 0.3 times that of urea in second-harmonic generation has been measured at 1295 nm. An X-ray crystal structure of 6, 1:1 complex of 1 with (-)-2 in ethanol, reveals that all the molecular dipoles are aligned in the same direction (i.e, a polar crystal), but 6 has modest nonlinear optical properties (ca. 0.4 times that of urea).

Research on electron transfer in the microenvironment of the biofilm by scanning electrochemical microscopy

Microorganisms exploit extracellular electron transfer (EET) with external minerals during their growth. This process is accompanied by the conversion of chemical energy. Direct electron transfer (DET) from the microorganisms to solid electron acceptors via membrane-bound cytochrome c enzymes or conductive nanowires/pili has been reported. In previous studies, mediated electron transfer (MET) has also been demonstrated to occur through electrochemically active metabolites acting as redox mediators. The microorganisms with EET capabilities have been harnessed for bioelectrochemical systems (BESs) in the bioremediation of environmental contaminants and the production of biofuels and nanomaterials. Electron transfer at the electrode biofilm/solution interface is one of the core phenomena occurring in BESs. The study of the redox reactions occurring in the microenvironment of the biofilm should elucidate the mechanism of microbial EET, which will then help improve the electron transfer efficiency of BESs. The composition of a biofilm is complex and contains many redox secreta and extracellular polymeric substances. Therefore, the specific current generated from the DET or MET pathways cannot be solely detected using classic electrochemical methods. In the present study, the interfacial electron transfer of Shewanella oneidensis MR-1 on an ITO surface was investigated. Cyclic voltammetry (CV) was first applied to study the redox properties of Shewanella and its interaction with ferrocenylmethanol (FcMeOH), which served as an exogenous electron mediator. The cyclic voltammograms showed that the oxidation current of S. oneidensis MR-1 was dramatically enhanced in the presence of 0.01 mmol¡¤L-1 FcMeOH compared to a control, i.e. bacterium-free ITO. This can be explained by the ability of S. oneidensis MR-1 to reduce FcMeOH+ during the positive scan. These results also showed that FcMeOH was a good redox mediator and capable of transferring electrons between the electrode and the bacterial cells. In addition, using the penetration mode in scanning electrochemical microscopy, the current generated from the MET by FcMeOH was collected using a microelectrode. Examination of the approaching curve showed that the current started to increase when the tip was approaching the solution/biofilm interface, providing positive feedback for the FcMeOH-mediated electron transfer between the microelectrode and the bacterial cells. The electrode biofilm/solution microenvironment was also detected, showing the thickness of the solution/biofilm to be 500 mum and the thickness of the biofilm to be 1100 mum. This study indicates that scanning electrochemical microscopy can be used in studying microbial MET. It also provides insight into the electron transfer mechanism of the microbial metabolism from a physical chemistry perspective.

Redox active alkenyl-bridged bi- and trinuclear arene-Cr(CO)3-complexes by Horner-Emmons-Wadsworth olefinations

Alkenyl-bridged arene-Cr(CO)3-complexes 2 are readily synthesized in good yields by Horner-Emmons-Wadsworth (HEW) olefinations from Cr(CO)3-complexed benzylphosphonates 1 and organometallic aldehydes. The resulting bi- and trinuclear homo-and heterometallic complexes display a strong electronic coupling between the metal fragments as shown by a strong correlation of the CO resonances in the carbon NMR spectra and the chromiumcarbonyl metal-ligand charge transfer (MLCT) bands in the UV/vis spectra. Furthermore, the electrochemistry of the oligonuclear complexes 2 was investigated by cyclic voltammetry.
